As mentioned in this earlier post about the Kelly Well Company - 1915: Kelly Well Drilling Products & Services - William Kelly held the patents for concrete well casings technology that was used all over the U.S. until PVC casings took over in the 1970s.

A little digging at the U.S. Patent Office has turned up copies of the documents involved in awarding William Kelly the patent for a well strainer.

We've also dug up the documents regarding the 1935 patent for a method of well construction.
